I got this English Oak from a local club member. He thinks he is too old to start new projects

Any hoo, I need some advise on what direction to go with it. there is a small amount of reverse taper that I hope will correct itself over time. But Im not sure if I should carve the trunk into a twin trunk as I have seen done on many trees or keep the broom style and refine it.
Any thoughts are more than welcome.
Cheers
